The cause of the problem is shown in the crash report you posted: at least one of the level_sponge.dat files is probably corrupted. You can either

  • replace it with a backup,
  • delete it and rename the level_sponge.dat_old backup file (if present),
  • or just delete it and let it regenerate (losing some sponge-specific data).

You might need to do this with several files (there’s one in each world folder); the corrupt ones are often 0 bytes in size.
